He received the CORE Award for Outstanding Research Contribution in 2024, IEEE AI's 10 to Watch Award in 2023, Eureka Prize shortlist for Emerging Leader in Science in 2023, ARC Future Fellowship Award in 2022, Faculty Early Career Research Excellence Award in 2021, the Top-40 Early Achievers by The Australian in 2020, and the ARC DECRA Award in 2018. He also received multiple faculty awards, e.g., from OPPO and Meituan. Tongliang is also very proud of his talented students, who have made/are making/will make significant contributions to advancing science. They have also been recognised by many awards, e.g., Google PhD Fellowship Awards.

Tongliang Liu is the Director of Sydney AI Centre and an Associate Professor at The University of Sydney, Australia; an Affiliated Associate Professor in Machine Learning with Mohamed bin Zayed University of Artificial Intelligence, United Arab Emirates; a Visiting Professor of University of Science and Technology of China, Hefei, China; a Visiting Scientist of RIKEN AIP, Tokyo, Japan.

His research interests lie in providing mathematical and theoretical foundations to justify and understand machine learning models and designing efficient learning algorithms for problems in the field of trustworthy machine learning, with a particular emphasis on

  • Learning with noisy labels,

  • Deep adversarial learning,

  • Causal representation learning,

  • Deep transfer learning,

  • Deep unsupervised learning,

  • Statistical deep learning theory.

He is a Co-Editor-in-Chief of Neural Networks. He is regularly the meta-reviewer of ICML, NeurIPS, ICLR, UAI, IJCAI, and AAAI. He is an Action Editor of Transactions on Machine Learning Research, an Associate Editor of ACM Computing Surveys, and on the Editorial Board of Journal of Machine Learning Research and the Machine Learning journal.

We are looking for visiting scholars for Asian Trustworthy Machine Learning (ATML) Fellowships. See more details here.
